I recently aquired a new laptop; A Dell Latitude D630 which has a C2D T7300 as cpu. Just about the first thing I did was enable powerd, allthough that doesn't realy seems to work; the CPU-speed doesn't decrease when the system is idle ( or at least dev.cpu.freq is always 2001 where at my previous laptop it went to an lower level when the system was idle ) . The freqlevel is still at 2001 when `top` shows the CPU is 97% idle. Anyone else with a C2D cpu running powerd which has this problem or am I just doing something wrong : frank@Rena# uname -a FreeBSD Rena.FStaals.net 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Sat Oct 13 12:59:51 CEST 2007 root@Rena.FStaals.net:/usr/obj/usr/src/sys/GENERIC i386 frank@Rena# cat /etc/rc.conf | grep powerd powerd_enable="YES" powerd_flags="-a adaptive -b adaptive -i 85 -n adaptive -r 65" frank@Rena# dmesg -a | grep powerd Starting powerd. frank@Rena# sysctl -a | grep freq kern.acct_chkfreq: 15 kern.timecounter.tc.i8254.frequency: 1193182 kern.timecounter.tc.HPET.frequency: 14318180 kern.timecounter.tc.ACPI-fast.frequency: 3579545 kern.timecounter.tc.TSC.frequency: 2001000000 net.inet.sctp.sack_freq: 2 debug.cpufreq.verbose: 0 debug.cpufreq.lowest: 0 machdep.tsc_freq: 2001000000 machdep.i8254_freq: 1193182 machdep.acpi_timer_freq: 3579545 dev.cpu.0.freq: 2001 dev.cpu.0.freq_levels: 2001/32000 2000/31000 1750/27125 1600/22000 1400/19250 1200/13000 1050/11375 900/9750 800/10000 700/8750 600/7500 500/6250 400/5000 300/3750 dev.est.0.freq_settings: 2001/32000 2000/31000 1600/22000 1200/13000 800/10000 dev.est.1.freq_settings: 2001/32000 2000/31000 1600/22000 1200/13000 800/10000 dev.cpufreq.0.%driver: cpufreq dev.cpufreq.0.%parent: cpu0 dev.cpufreq.1.%driver: cpufreq dev.cpufreq.1.%parent: cpu1 dev.p4tcc.0.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1 3750/-1 dev.p4tcc.1.freq_settings: 10000/-1 8750/-1 7500/-1 6250/-1 5000/-1 3750/-1 frank@Rena# dmesg -a | grep CPU CPU: Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz (1994.45-MHz 686-class CPU) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0: <ACPI CPU> on acpi0 p4tcc0: <CPU Frequency Thermal Control> on cpu0 cpu1: <ACPI CPU> on acpi0 p4tcc1: <CPU Frequency Thermal Control> on cpu1 SMP: AP CPU #1 Launched! frank@Rena# dmesg -a | grep cpu cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu0: <ACPI CPU> on acpi0 est0: <Enhanced SpeedStep Frequency Control> on cpu0 p4tcc0: <CPU Frequency Thermal Control> on cpu0 cpu1: <ACPI CPU> on acpi0 est1: <Enhanced SpeedStep Frequency Control> on cpu1 p4tcc1: <CPU Frequency Thermal Control> on cpu1 hw.acpi.cpu.cx_lowest: -- -Frank Staals
